Unit would not start up

Conclusion was that either the control panel or the noise filter (an electrical fuse apparatus)was bad. Disconnected the water line, turned off power, and pulled unit out from cabinets. Determined that voltage was going into the noise filter (white harness) but almost no voltage coming out (red harness). Ordered noise filter. Hardest part was removing old noise filter from dishwasher frame without removing the whole unit from cabinet and turning upside down.One screw holds the part in the frame. With power off, I used a very small ratchet with phillips screw driver. Pried unit out with screw driver on side to the panel front. It has a retaining tab there.Installation was the reverse. Instead of putting screw back the way it was originally installed, I screwed it in from the outside of the frame. Much easier and just as solid. Tested unit with power on. Hooked up water line. Works great. Note: LG dishwahers have a high repair rate and that this part has a high failure rate. This LG unit was two years old. Never had to fix my 15 year old Sears dishwasher. It still works to this day. (I gave it to my daughter.)

First, PartSelect is great!; fast,& accurate. 1. Inside the dishwasher: remove trays. Remove (A050) lower water sprayer from bottom by pulling up. Remove (F191) top sprayer assembly by pulling away from clip holders. Remove (M110) by removing the holding screws. This part cover the whole sump and has kind-of an open screen circling the unit. Now you will see the white plastic impeller (M120) which is attached the the motor with one Phillips head screw. WARNING. The Phillips head screw (holding the impeller in place) is a REVERSE THREADED SCREW. Turn the screw CLOCKWISE to remove it. Then remove the impeller from the motor shaft. Underneath and outside the washer: Remove the bottom plate. Finally remove the motor by unscrewing the four holding screws and electrical wiring.

BROKEN ROLLER ON THE LOWER TRAY.

THESE WERE A SIMPLE SNAP ON ITEM. IT TOOK LONGER TO CARRY THE PARTS FROM THE PORCH THAT TO INSTALL. RECENTLY PURCHASED HOUSE. ROLLERS WERE MISSING DUE TO OVERLOAD?? REMOVED THE REMAINING ROLLER PIECES. CLEANED AND STRAIGHTENED THE AXLE SHAFTS, SPRAY LUBED THE TRAY AND SNAPPED THE NEW PIECES IN PLACE.

Dishwasher leaks from door region during washing cycle.

Old door seal appeared ok, no rips and seated evenly all around. Pulled that seal out and replaced with new. Seated new door seal after wetting inserted lip. Tested...leak greatly reduced, but still dripping. Removed seal, placed a rubber rope (same rope used for screening) within the tub recess, then reseated new seal. leak ceased. Also replaced the reservoirs on the left side of the cabinet (guide assembly). Old reservoir had debris within so decided to replace. Used regular pliers for the 3 hose spring clamps underneath, and a pair of large neede nose pliers for the fill flange (regular thread).

racks were rusted

parts were not exact match with original, even though ordered from schematic. had to bend the replacement part slightly so it would fit into holder pieces. this took about 10 minutes as I was trying to be careful not to break/cut the coating (which would then lead to rust again). Once the piece was bent, just snapped the rack into place.

Door is to heavy to hold

The connector assembly connects to a spring to hold the door from falling down. You need to disconnect the power cord, the water line and the drain hose before you move the dishwasher out the kitchen counter. There are several screws that hols the dishwasher in place top, side and bottom. Removed all screws then pull the dishwasher out very slow. Take the side panel by un-screwing all the screws around the panel in my case where five screws (two in the front so you have to open the door to get to them). You need to keep the door down to connect the assembly to the door bracket and the go through the pulley then to the spring, very easy. Put the side panel back and push the dishwasher in place use the same screws and reconnect the hose the water line and the power and you are done.

When I read the book it said that the HE stood for Heating Element. You can easily get to it from the bottom. (leason learned after getting to it from the top) Test the element for continuity. Second Test to see if power is being fed to Heating Element with dishwasher turned off. Expensive Lesson Learned After Burning up three Heating elements (including the original) The Circuit board went bad and was sending power to my Heating element with dishwaher off. It was burning up the heating elements in about 30 seconds. $150 dollars of parts and shipping dishwasher is still not working. Waiting to see if LG will honor there 5 year warranty on the Control Board.

Dish washer would shut off mid cycle.

Check the motor and discovered roughness when you turned the shaft. I assume there was a bearing problem. I ordered a new motor from part select and upon the replacement washer is working great! Thanks part select, my part arrived in a timely manner and you guys saved me approx. $500. Thanx again. Richard Sansom

Door lift assist broke

removing the dishwasher from under the counter I accidentally broke the mounting braket, to investigate/discover the door lift cord had frayed and broken. Parts were easy to locate and the costomer service was friendly. Installation was a breeze and perfectly intuitive. Not a Problem. thanks for being there, hiring a repairman would have been expensive.

door connector broke, so door just flopped open

pulled the dishwasher out, removed the side panel. It was very easy to replace the connector once the dishwasher was out and the side panel was removed. There are about five screws to remove the side panel. I replaced the unbroken connector on the other side since I had the dishwasher out.

The connector that provides counter weight for the door snapped and the door would flop open, it weighs a lot

Undo screws holding dishwasher in place, two screw just inside door one each side, should be covered with plastic cap. Slide dishwasher out, there is a spring on each side of the door connected through the connector to the door and cabinet. Slide connector our, install new one, slide disher back in, reattach screws holding dishwasher in place and your done.
